veg oil in Zexel,is it a bosch copy?

[jezmondoveg]

Sorry to throw so many posts on here !

Iam a newbe to terranos ,but iam a bit crackers on using veg oil in cars.

Before i take the plunge i want to know ive got the right fuel pump.

Been twin tanking my bongo,but would rather single tank the terrano,poss with a heated filter and heatexchanger.


Just need to know is the Zexel pump any worse on veg oil than a bosch or is it a bosch copy and still fine. will prob get a terrano arround 1999/2000 year.

Will have about 4k to spend,but this is one of the the main things iam looking for,a fuel pump ok to use veg oil in.

Thanks again for your time guys,ive now started seeing how many t2 about,saw 6 today! oh dear think iam hooked already and not evn got one yet!

Zexel pumps are in only SOME terranos, I think that most have the Bosch. I have a zexel pump and a Hitachi maf and I believe that the Bosch pump vehicles have a Bosch maf. These are not interchangeable as the wiring is different.

Now your question, it as been said that the zexel is not suitable, but people on this site have been using it including myself. I have been using 50/50 asda sunflower/ derv during the summer and all was well although when it went cold I had lumpy running when cold. I then switched to asda vegetable oil when they changed the discount to the veggie.

I am not using it at the moment as I believe its to cold.

A discovery I have made which may interest you about asda oils. I have done a test during the cold weather. The sunflower which looked the thinnest normally soon turned to a solid at the first sign of cold whilst the vegetable that looked slightly thicker normally never changed its viscosity even when I left a container out all week in the snow with temperatures dropping below minus 8c! This was a surprise to me. regards bri

Thanks thats great,will have to make sure its a bosch then!

Interesting stuff. Your experiment may have answered how I got through the winter using vege oil :thumb2

Yes Dave I was surprised, I had a jar of sunflower outside for some time and it waxed and then turned solid, I then put a bottle of veggi with it expecting the same result but there it is looking just like the bottle I have in the garage, they are both the same. Meanwhile a five gallon of water froze solid, along with my pond.. bri

Can i add to this...

Ive been doing some tests for a filter company going as low as 0.1 micron yes 0.1 not 1!

and we found that the cleaner the oil the better it lasts in the cold,i had a jam jar full last 48 hours in freezer and was not solid but thicker.after 24 hours was hardly any different that when it went in there

Also recovery times back to clear oil and runny are quicker when using super clean oil.

And atfer loads of emails,we found that new virgin oil is only down to 10 micron for food use,so by cleaning new oil further may help in cold conditions as well.

I only use waste oil.

interesting stuff. My test when I continued through the winter with svo (+diesel) was far less scientfic. The 15 litre barrels were stored in the shed and if they didnt look liquid enough they didnt go in the car. I dont think i had 100% diesel in at any point during the winter.

And atfer loads of emails,we found that new virgin oil is only down to 10 micron for food use,so by cleaning new oil further may help in cold conditions as well.

They dont clean the bits out so the cloudy virgin stuff appeals to the trendies




I presume all the experiments were on your twin tank system?

How do the filters hack it in the colder weather and what is the corolation or pattern between temp and filter ability (over an above they find it harder when the oils thicker:doh) ???

At what temp (generally) does it stop mattering f you can filter it because te injectors are stuffed ?

At what temp/filtration with a specified standard or brand of oil do they problems come in, more to the point is there a range of filters available so they can be swapped like say winter / summer tyres?????

After all the debate on here I reckon theres more than me interested in those points :thumbs

The Bosch system is also alot cheaper to fix when it goes wrong!

 

[jezmondoveg]

The way you do it is a great idea,i prefeer to mix outside tank if doing it on a unconverted engine.

Yes i have a twin tank kit(easy to make diy) mine is from diesel veg,there is a temp senser on coolant line and when upto 55 oc it allows switching over to veg.and a glow plug in loop bumping up loop temp if cold air hits it.

when you need to shut down it flushes out veg with diesel,with a adjustable timer,that flushing diel/veg mix goes back to you veg tank..well that how ive been doing it but that may change on next installation.

We have not added extra diesel to main tank yet on having the flushmix thinning the main veg oil in tank.Thats evenin these cold conditions!!

Next time i wouldnt loop the system as its a bugger if you get air ingress as its stuckin the loop,i am going to have returns to both diesel and veg so when on the selected fuel any air gets taken back to that tank,ALSO when on veg the return heat helps keep the tank nice and warm.


Loads of differnt ways of twin tanking, i have heatexchanger b4 standard car filter so doing that keeps the filter warm.

But if i twin tank again i will put my coolant heated filter b4 heatexchanger,heated filters are good on a twintank kit as when on diesel the veg heated filter is warming up.Use the standard diesel housing in your car for diesel only .


Some guys even have a coolant heated tank,but not really needed in thr uk,just if gets cold add a bit of diesel to veg in main tank seems good enough.



On filtration,i filter wvo from an ibc,i fill with old oil and settle out for a month ,then filter off the top with a propper gear oil transfer pump,though 10 inch filter housings,20,1,0.5,0.1 micron,thats cold not heated oil,i can either go direct to van or into a 20 ltr can whith a hand pump,
At the moment it takes under 5 mins to draw off and filter 20 ltrs of oil,ok its seems slow but quick in summer..


I have also found the more passes you do on what ever type /make of filter it is it imporoves it no end,at one point i was double filtering oil .




But the reason why iam asking you guys on here is advise from your end of things,i may only sinle tank terrano=less probs that may ocour with kit,aim running with the idea of just a coolant heated heatexchanger and using standard nissan car filter,add in diesel to main tank.That would keep teh filter clear and send heat to tank.
But also thought of adding a kenlowe block heater that plugs into a 240v power supply thus heating coolant ready to start on a warm engine,was going to rig it so a seperate pump flows fuel from tank through heat exchanger and back to tank,giving mw a nice warm tank of fuel before seting off.


**Just wonder how much diesel you add to veg this time of year?and does it run rough when cold? and i take it the enginge is indirect injection? most of you seem not to have a twin tank setup.

Interesting stuff.

I couldn't find a suitable temp activated solenoid when i considered twin tanking. All manual

I stuck to single tank and mixing by judgment. It wasn't as cold the winter I was using svo but i don't think if i recall ever going more than 50/50 with diesel and up to 100% svo. The standard nissan filter hacked it but I did install a heater in line just before the pump.

I notice a few people have put these heaters in various locations , i put it there because its close enough to help the pump and injectors ad tucked out of the air flow as opposed to in an open space looking nice but in the cold airflow, it was as shielded as far as poss with the radiant heat from the block helping out.It seemed to work very well.

That saw me through all of winter 08/09 with no problems other than one occasion when the temp dropped some amazing and unexpected amount. Even then lumpy running the order of the day until some millers and diesel could be chucked in

I did consider the kenlowe system but never went ahead. Its nice im sure to have but expensive and as the main running problems would come from cold tank/fuel/filter/fuel lines feeding the engine im not sure it would solve anything when other measures are cheaper, easier and in place :thumb2


I ran on svo for fun but also saved a fortune doing so :clap:clap:clap

 

[jezmondoveg]

can help you if you want to go for it again.

Cant be bothered to be honest. Mine is a common rail and needs injectors etc changing.

The expense of preparing it would easily outweigh the savings I could make and im not eco friendly enough to do it on principle. I quite enjoy telling the anti 4x4 brigade that i drive one with the worst emissions going..................and its still on the cheaper road tax :lol:lol:lol:lol:lol:lol:lol:lol:lol:lol:lol:lol

 

[jezmondoveg]

You put veg in a common rail??? wow iam suprised you still have that car!and not wrecked it..NEver put anything else part from diesel in one...

what year terrano became a common rai?

Its not terrano and it hasnt had svo in it :doh:doh

 

[jezmondoveg]

PHEW!

did they ever do a terrano in common rail?

tbh I dont know / cant remember. I think so though

 

[jezmondoveg]

prob get a year 2000 ish anyway..can see a terrano being common rail at that age..

 

[danielj]

Interesting discussion. The Terrano 2 reg 2000 I have is definately not common rail.
When you say you use waste veg oil is that after you mix chemicals with it to make bio-diesel and then filter it or do you just do the filtering process you mention?
I don't know much about this subject but have been looking into it with diesel gone up about 6 cent here in the past three weeks or so. Cheapest I can find pure plant oil is Euro 1.09 a litre if buying in bulk and collecting myself from the supplier about 60 miles away. Veggie oil is Euro 1.47 a litre in Lidl and Tesco (gone up from Euro 1.33 in about three weeks for some reason).

 

[jezmondoveg]

new oil can be still got for 50p per ltr if you buy an ibc full =1000ltrs

Think macro is still 85p per ltrs at moment

good prices re still out there if you look on svo
